FABRIC.

Specification of Letters Patent.

Patented Got. 16, 1917.

Application filed May 1, 1916. Serial No. 94,540.

To all whom it may concern:

Be it known that I, J AMES WV. SNEDEKER, a citizen of the United States, and residing at Adrian, in the county of Lenawee and State of Michigan, have invented a new and Improved Fabric, of which the following is a specification.

This invention relates to structures formed by interlacing metal rods wherein a number of the rods are bent back and forth so that in passing across the structure each bent rod interlocks with the rods on each side of it alternately, and the object of this invention is to produce a fabric in which angular loops project from one or both sides of the general plane of the structure.

This invention consists of a fabric formed of inter-engaging metal rods of which alternate rods are straight and the others bent to form polygonal helices, the helically-shaped rods having the axes of the helices substantially parallel with the straight rods and said helically-shaped rods engaging the helically-shaped rods and straight rods on each side.

In the accompanyin drawings, Figure 1 is an end elevation of a completed fabric embodying this invention. Fig. 2 is a perspective view of one corner thereof. Fig. 3 is a plan of one of the bent rods. Fig. 4: is an end elevation of one bent rod and a part of another. Fig. 5 is a perspective view of a bent rod. Fig. 6 is an end elevation of a modified form of this fabric.

Similar reference characters refer to like parts throughout the several views.

The fabric shown in the drawing may be considered entirely apart from the frame and consists of metal rods that have been wound upon a polygonal mandrel, triangular or square in cross-section preferred, and then stretched out so as to constitute what may be termed polygonal helices. As shown in Figs. 3, 4 and 5, each rod 1 consists, when wound on a triangular mandrel, of connected sections 2, 3 and. 4, lying in three planes that define a triangular prism, the sections extending at an angle to the lines of intersection of the planes.

The plane of the sections 2 of each rod is Copies of this patent may be obtained for five cents each, by addressing the continuous with the corresponding planes of the other bent rods, and sections 3 and 1 of each of the rods lying in the other two planes constitute angles 5 which project from one side of the plane of the fabric.

In the fabric shown in Figs. 1 and 2, the angles 5 project from the far side, and each helix not only interlaces with the adjacent helices but it also loops around the straight rods 6 which are employed to give the fabric greater stiffness. These rods 6 may be omitted if desired.

The outer rods 1 may wrap around frame members 7, while frame members 8 of sheet metal may be bent down onto the ends of the rods 1 and 6 that may be twisted together.

The structure shown in Figs. 1 and 2 may be employed for various purposes, such as cattle guards for railway crossings, harrows for cultivating land, and door mats, depend ing upon the diameters of the rods and the size of the meshes.

In Fig. 6, the rods 9 have been wound on a mandrel that is square in cross section, and these rods 9 inter-lace with each other and with the straight rods 10. This particular structure is peculiarly adapted for door mats.

I claim:

1. In a metal fabric, the combination of alternately arranged straight rods and helically-shaped rods having the axes of the helices substantially parallel with the straight rods, the helical rods being in the form of three-sided helices engaging the helices and straight rods on each side thereof, one side of each of said helices being in the same plane.

2. In a metal fabric, the combination of alternately arranged straight rods and helically-shaped rods having the axes of the helices substantially parallel with the straight rods, the helical rods being in the form of polygonal helices engaging the helices and straight rods on each side thereof, the planes of the two sides of each helix on one side of the general plane of all the straight rods meeting in a line.
